20 ECU versions are currently supported from all regions.

Mazda Diesel Features

Mazda Diesel provides access to a wide range of calibration options for the OEM ECU, such as:

  • Fuel Injection Quantities
  • Fuel Pressure
  • Boost Control
  • Torque Control
  • Injection Quantity Limiters
  • Turbo Dynamics Control
  • Sensor Scaling
  • Rev Limiters
  • Speed Limiters
  • High speed CAN datalogging including DPF related parameters
  • DPF Tool, including Force DPF Regeneration feature
  • Injector Coding Tool
  • Oil Service Counter Reset Tool

Tests have shown that for the the 2007 model 2.0ltr Mazda 6, power can eassily be increased from 143bhp to 175bhp. Correspondingly, torque can be raised from the standard 270lbs.ft (360Nm) to over 300lbs.ft (400Nm+).
Furthermore, the 150PS 2009 2.2ltr Mazda 3 can be tuned to 190PS with over 450Nm Torque, outshining the factory 185PS model.

Sensor calibration parameters for intakes and exhaust systems mean the ECU can be safely tuned for whatever the hardware can produce, providing you with a huge range of tuning options.

Live Data

When connected to a car, ProECU Mazda Diesel can offer real time data and map tracing.
The following data is available from the 'Live Data' tab of the ROM file being accessed. This data is accessed directly from the ECU in real time.

  • RPM: Engine speed. (Revolutions Per Minute)
  • Fuel Rail Pressure
  • Exhaust Gas Temp
  • Wastegate Duty
  • DPF Regeneration
  • Equivalence Ratio – Lambda

The below screenshots shows some example data for 30 out of approximately 95 live data parameters:

It is possible to log the data shown during Map Access mode for analysis in DeltaDash or ProECU.
It is then possible to customise the way the logged data are displayed using the Time Graphs, Data Table, Custom 2D Graphing, and Custom 3D Graphing tabs in the Log Viewer, as shown below:

Mazda Diesel Tools

ProECU provides a specific Mazda Diesel ECU tool allowing you to perform Oil Ratio Resets, Fuel Pump Reset and DPF Pressure Sensor Reset. The newer 2010 2.2 Litre models also have a read & write injector codes function for injector calibration. Further features for DPF reset and re-installation are currently in development.

Force DPF Regeneration

This can be used to manual force a regeneration of the Diesel Particulate Filter (DPF/FAP).

Install New DPF

Used when installing a new DPF filter.

Reset Oil Ratio

This important tools is required after an oil change service. This prevents the warning light on the dashboard.

ETB/EGR Initialisation

Electronic Throttle Body (ETB) and Exhaust Gas Recirculation (EGR) Initialisation should be used after installing new ETB or EGR parts.

ECU Reset

This tool will reset all learnt and initialised values.

Reset Tools

Learnt values for the Fuel Pump, Injectors, MAF Sensor and the O2 Senor can be reset.

Read and Write Injector Codes

This tool allows for the correct configuration of new injectors.
